For reference: I'm running Debian/testing, Iceweasel 3.0.9 (unbranded firefox), Debian packaged v 3.55 of mplayer plugin, and mplayer 1.0.rc2svn20090412 (packaged by debian-multimedia.org). This seems to have already been reported as Ubuntu bug #360222 [1], and Arch Linux bug #14155 [2]. I get the following typical output when running from a terminal: ADDED URL: harrypotterhalfbloodprince-tlr4b_h640w.mov code: 42 speed -1 and then the segfault. I used this text as a starting point for debugging and luck was on my side :-) The crash happens at plugin-list.cpp, line 414, during the call to memmem. The cause is a typo in the exit condition at line 411 - 'p' appears instead of 'buffer' (see attached patch), so that we get to line 414 even if there's no next "rmda" (consider lines 348, 418). All line numbers refer to the code from the daily snapshot. I'm guessing that something must have changed at apple.com to trigger this specific code path. In any case, the patched plugin seems to work nicely at my end. Cheers, Avi.
